Hi all!I'm looking for a led to use as a "lamp" in the darkness for an Epaper screen.I'm using a wemos D32 pro board working at 3.3V (I have the possibility to have a 5V output too).The led must be placed in a 1x6x1.5 cm box so it should be quite small.I'm looking for the brightest possibility taking into account these constraints.(Of course there is always the possibility to use an external power source but this is not what I'm looking for)Thank you in advance
Would help if you told us where you have looked.Paul
Cut down a 12W luxeon star sized emitter? You never mentioned heatsinking, that is going to bethe constraint to worry about, 12W is available in small packages and 12W LED will light up a smallroom...
Have you looked at the LED backlights like those offered by adafruit?https://www.adafruit.com/product/1621
